Trying to learn about Soccer, World Cup edition

I’m watching the Columbia vs. Greece game as I type this.  I think the big thing that prevents me from really enjoying it is that there seems to be no chance of a sudden score from anywhere on the field.  I mean, in American football (which I understand is called “gridiron” by the rest of the world–much better name for it.) you occasionally see 99-yard touchdowns.  It’s unusual, but still it could happen.

But I don’t think you ever see goals that go the length of the field in soccer.  It might even be against the rules, for all I know–never was clear on where you were allowed to score from, exactly.  Also–and this may well be a mistaken impression–but somehow a 2 goal lead in soccer, like Columbia currently enjoys, feels much bigger than a 14-point lead in a gridiron game. I don’t know if it is, but it feels like it.  I’d be interested to see the in-game win probability comparisons, though.

What's your stake in this, cowboy?
